Kuenzanisa kwehwanda nedzimwe manhara

Maperi anoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri, kusanganisira marara, zvigadzirwa zvekuvaka, zvizhinyinji, chikafu nemushonga. HydroxytHyl Cellulose (HEC) idanho rakakosha iro rakakwezva kutarisisa kwezvinhu zvakasarudzika zvakasarudzika uye zvinoshandiswa.

1. Kuumbwa uye kunobva
HEC ndeye cellulose ether yakagadzirwa nekuita zvakasikwa cellulose ine ethylyone oxide. Iyo isiri-ionic mvura-yekunyora polymer ine yakanaka makemikari kugadzikana. Mukupesana, mamwe manhamba ane zvinyorwa zvakasiyana siyana, kusanganisira zvinotevera:

Zvisikwa zvePolysaccharide: senge xanthan gamu uye guar gamu, aya manhara anobva kune zvidyarwa zvezvirimwa kana microbial kurudziro uye kuve nekudzivirirwa zvakaringana.

Synthetic thickeners: senge acrylic acid polymers

Protein manhamba: senge glatin, inonyanya kutorwa kubva mumatikiti emhuka uye akakodzera chikafu nemushonga.
Hec ine zvese zvinodzivirirwa zvakatipoteredza kwemasikirwo emusangano uye kuita kwakanakisa kwekugadziridzwa kwemakemikari mukuumbwa, kuwana chiyero pakati pehushamwari hwezvakatipoteredza uye kuwanda.

2. Kuita kwakashata
Hec ine maitiro anotevera mukuita kwakasiyana-siyana:

Solubility: Hec inogona kunyungudutswa mumvura inotonhora uye mvura inopisa kuti iite gadziriso yeVicipaus Viscous neyekukurumidza kupaza mwero. Xanthan Gum inowanzoda Shear Simba rekubatsira kupaza, uye mhinduro inogona kuve neyakaomeswa.
Yakakura viscosity yekugadzirisa renji: nekugadzirisa iyo molecular uremu uye degree rekutsiva kwehisheni, zvigadzirwa zvine makisi akasiyana ekuvenga zvinogona kuwanikwa kuti usangane nezvinodiwa zvakasiyana siyana zvekushandisa. Mukupesana, iyo viscosity yekugadzirisa huwandu hweGuar gum ndeyekuderera. Kunyangwe acrylic acid polymer ine yakanaka yakanaka mhedzisiro, ine hanya zvakanyanya nePR kukosha.
Shear Performance Performance: Hec ine inonaka shear yekufungidzira maitiro uye yakakodzera kune dzimwe nguva ipo pane imwe misangano yekuumbwa inoda kuchengetwa. Xanthan gamu ine yakakosha pseudoplastical uye yakakodzera kushandiswa kwejasi uye emulsions dzekudya.

3. Kugadzikana kwemakemikari
Hec ine kugadzikana kwakanaka mune yakawandisa pH range (2-12), uye inodzivirira kupisa kwakanyanya uye munyu, uye kwakakodzera kune zvinoshandiswa mumunyu-ane masisitimu emunyu kana masisitimu ekushisa. Mukuenzanisa:

Xanthan Gum ine zvirinani kupokana nemunyu pane hembe, asi inonyudzwa nyore nyore pasi peiyo acid yakasimba uye alkali mamiriro.
Acrylic Polymers ane hanya neAcid naAlkali, uye vanokundikana kutadza pasi pemamiriro ekunze emunyu.
Kugadzikana kwemakemikari kweakasikwa polysaccharide mumatambudziko akanyanya uye oxidative mamiriro kazhinji haana kunaka sehomwe.

4. Misiyano munzvimbo dzekushandisa
Coatings uye zvigadzirwa zvekuvaka: Hec inowanzoshandiswa mumvura-yakavakirwa mvura, putty poders uye monganda, ichipa miganhu yakanaka uye yekuchengetwa kwemvura. Xanthan gamu inoshandiswa zvakanyanya mune mvura yemvura, kunyanya nekuda kweshekita yayo yekufungidzira.
Cosmetics uye Mazuva ese Zvigadzirwa Zvigadzirwa: Hec inogona kupa ganda rakatsetseka kunzwa uye yakanaka kwazvo mhedzisiro, uye inoshandiswa zvakanyanya mune yechiso kuchenesa uye marara. Acrylic polymers ine mukana mune ger zvigadzirwa nekuda kweiyo yavo yakakwira transparkarency uye kugona kwakasimba kugona.
Chikafu nemushonga: Xanthan Gum uye Guar Gum zvinoshandiswa zvakanyanya mukudya nemushonga nekuda kwekutanga kwavo uye kwakanaka kugona. Kunyangwe hec chichigona kushandiswawo mukugadzirira zvinodhaka-zvinogadziriswa, ine mashoma ekudya-giredhi zvikumbiro.

5. Mutengo uye Mutengo
Hec ine hukama hwakatipoteredza uye kusvibiswa nekuti inogadzirwa yakavakirwa pane zvakasikwa cellulose. Maitiro ekugadzira emahedheni pherylic polylic zvine simba rakakura pane zvakatipoteredza uye zvakaoma kushatisa mushure mekuraswa. Kunyangwe Xanthan Gum uye Guar Gum mune zvakatipoteredza hushamwari, mitengo yavo inowanzo kukwirira kupfuura yehec, kunyanya yezvigadzirwa zvakagadziridzwa mune zvakakosha zvikumbiro.

Semunhu akasarudzika aine maitiro akajeka, hec ane zvakasarudzika mapoka akawanda. Kuenzaniswa neXanthan gamu uye guar gum, hec inokwikwidza mukugadzikana kwemakemikari uye mutengo-kushanda; Kuenzaniswa neAcrylic polymers, hec ndeyezhinji zvakatipoteredza uye ine shanduko yakakura. Mukusarudzwa chaiko, zvinhu zvakadai sekuita sekuita kwemakemikari, kurongeka kwemakemikari kunofanirwa kuve kwakanangana nekufungidzirwa zvichienderana nezvinodiwa chaizvo zvekushandisa kuti uwane zvakanakisa uye kukosha.
